Philadelphia Eagles wide receiver Riley Cooper got the biggest piece of Nick Foles' record-tying day on Sunday, hauling in five catches for 139 yards and three touchdowns in a 49-20 rout of the Oakland Raiders.

But the Foles-to-Cooper connection goes a little deeper, with Cooper's best three games of the season coming in Foles' starts. He's caught 15 passes on 19 targets for 247 yards and four touchdowns in Foles' three starts, compared to 10 catches, 24 targets, 206 yards and one touchdown in six other games.

Does that blossoming rapport with Foles make Cooper a must-add in fantasy football leagues?
